SOCKET-COVER WITH INTERCHANGEABL'E' SHADE-SUPPORT.

Specification of Letters Patent.

Patented Sept. 26, 1916."

Application filed November 13, 191 5 Serial No. 61,336.

T 0 all whom it may concern Be it known that I, LAURITZ W. ANDER- SEN, a citizen of the 'United States, residing at IVaterbu'ry, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Socket-Covers with Interchangeable Shade-Supports, of which the following is shades or glassware can be used in connec-- tion with the socket without unwiring the same or without removing the cover therefrom.

With this object in view the invention consists essentially in the employment of a socket shell cover preferably threaded at its lower end and adapted for connection with a threaded ring which is attached to the upper portion of the shade holder, that portion of the shade holder which receives the threaded ring being of uniform size, whereas the outer or shade receiving portion can be made of any size desired.

The invention consists also in certain details of construction hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification Figure 1 is a perspective View partly in section, showing the practical application of my invention; Fig. 2 is a vertical sectional view of the combination device, the dotted lines indicating a shade holder and shade of different size which can be exchanged for the size shown in full lines; Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2; and Fig. 4 is a detail sectional view illustrating the lower end of the socket cover and the upper end of the shade holder.

In constructing a device in accordance with my-invention, I employ a socket shell cover A of thin sheet metal having an aperture A at the upper end thereof for the conductor connection; and adjacent the lower end of this socket cover shell there is produced an outwardly projecting bead A This cover is adapted to be used in connection with a key socket, pull chain socket or keyless socket as desired, and in the drawings I haveshown the socket shell as slotted to receive the key of the ordinary key socket. Below the bead A ,'th e socket cover A is screw threaded as shown at A and if desired a plurality of vertical nicks A may be produced, there being four such nicks spaced at equidistant points.

In connection with the socket cover A, I

employ a shade holder B, which, at its lower or outer portion is provided with the usual sha'de'g'fastening screws for securing the shade or glassware C. Near its upper end,

the-shade "holder is formed with an in-' wardlvprojecting annular shoulder B, and within the upper end of the shade holder is arranged the connecting ring'D, which is screw threaded to correspond with the threads A of cover A, and at its lower end is provided with an outwardly projecting flange D which fits against and is soldered to the inwardly projecting shoulder B of the shade holder B; this flange connected at this point serving to maintain the threaded portion of the ring spaced from the extreme upper end of the shade holder, and the lower threaded end of the socket cover is adapted to fit into this annular space between the shade holder and ring when the socket cover and shade holder are brought together and connected as most clearly shown in Figs. 1 and 2.

In assembling the parts the socket is inserted in the cover A, the key fitting into the slot in the side of cover, and when the lower end of the cover is inserted in the annular space formed between the shade holder and connecting ring, it will be seen that the slotted end of the cover is surrounded by an unbroken ring or band which constitutes the top portion of a shade holder thereby strengthening the cover at the end.

By turning the shade holder a firm connection is established, and when the threads of the socket cover are nicked as shown at A, the threads of the ring D will also be nicked or indented at one point D so that in connecting the parts there will be an increased friction at each quarter turn providing substantially a locking action at that point.

After the shade holder and socket cover have once been connected, there is no danger of their accidental displacement, but when it is desired to substitute one shade holder for a different sized holder it can readily be accomplished by unscrewing the shade holder and substituting the other therefor, and it will not be necessary to disturb the socket or any of its connections.

It will thus be seen that I provide an exceedingly simple and highly eificient'combined socket shell cover and interchangeable shade holder.

Having thus described my invention, what I claim is 1. The combination with a socket cover threaded at its lower end, of a shouldered shade holder, a threaded ring having an outwardly projecting flange at its lower end adapted to be secured to the shoulder of the shade holder, whereby the threaded portion of said ring is spaced from the shade holder, said threaded portion being adapted to engage the threaded end of the socket cover.

2. The combination with a socket cover threaded at its lower end, said thread having one or more nicks produced therein, of a shade holder, a threaded ring having a nick adapted to engage the threaded end of the socket cover, said threaded ring having an outwardly projecting flange connected to the interior of the shade holder, the threaded end of the socket cover being adapted to rest between the threaded ring and upper portion of shade holder.

3. The combination with a shade holder, having an interior annular shoulder, adjacent its upper end, of a flanged ring arranged within the upper end of shade holder, the flanged portion of ring being secured to the interior annular shoulder, and a socket cover, the .lower end thereof resting between upper end of shade holder and ring and connected to said ring.

In testimony whereof, I hereunto aflix my signature in the presence of two witnesses.
